Introduction
Co-ordinate measuring machines (CMMs) have evolved from their origins in simple layout machines and manually operated systems, to
highly accurate, automated inspection centres.
A major factor in this evolution has been the touch-trigger probe and other forms of inspection probe, together with subsequent Renishaw
innovations such as the motorised probe head and automatic probe exchange system for unmanned, flexible inspection.
It all began with Rolls-Royce engines for the Anglo-French Concorde when a unique solution was required for accurate pipe measurement.
The result was the first touch-trigger probe: a 3D sensor capable of rapid, accurate inspection with low trigger forces. From this unique
starting point, Renishaw has established a range of precision probes and accessories for CMMs unequalled around the world.
Renishaw's success has been made possible by the close working relationship the company enjoys with CMM manufacturers and users.
The market is constantly striving to extend the frontiers of inspection technology. By close liaison throughout the design, development and
evaluation processes, Renishaw keeps in step with the market's needs ... and, in many cases, one step ahead.
From the Group's centre of operations in Wotton-under-Edge, Renishaw's products are exported to the world's leading industrialised
nations; a fact that has been rewarded by nine Queen's Awards.

Probe product overview
Renishaw's CMM touch-trigger probes detailed in this user's guide are designed to suit any CMM, but their individual characteristics are
outlined below:
TP1(S) A robust shank-mounted probe offering generous overtravel - ideally suited to manual CMMs.
TP2 - 5-
way
A compact probe allowing component penetration - ideally suited to CNC / DCC machines.
TP6 Complementing the TP2 series, but carrying longer and heavier styli, this probe is suited to general-purpose applications.
TP6A This probe has all the functions of the TP6 probe and in addition the patented Renishaw autojoint that permits fast probe
exchange without the need to requalify.
Renishaw also manufacture other touch-trigger probes which are not detailed in the user's guide.
For details of these and other Renishaw products, visit the Renishaw website at www.renishaw.com.
Principles of operation
The principle component of Renishaw touch-trigger probes is the kinematic location as shown below - a mechanical device that has the
ability to return the stylus ball to the same repeatable position following any deflection.
The kinematic location consists of a pivotal plate [1] that is spring-loaded against three bearing points [2] by a helical compression spring
[3]. These bearing points are formed by a combination of rollers and ball bearings.
Bearing points act as electrical contacts such that when the pivotal plate is deflected, the electrical circuit changes its characteristics and
causes the probe interface to send a trigger to the CMM controller.
Following this trigger event, the stylus ball must be removed from contact with the surface to enable the probe to return the stylus ball to its
repeatable position.

Applications guide
Stylus selection
In the majority of probing applications, to maximise accuracy we recommend that you:
Keep styli short and stiff
The more the stylus bends or deflects, the lower the accuracy. Probing with the minimum stylus length for your application is
recommended and where possible the use of one piece styli is suggested. Probing with excessive styli / extension combinations
should therefore be avoided.
Keep the stylus ball as large as possible
This will ensure maximum ball / stem clearance whilst providing a greater yet rigid effective working length (EWL). Using larger ruby
balls also reduces the effect of surface finish of the component being inspected.
EWL is the penetration that can be achieved by any ruby ball before its stem fouls against the feature. Generally, the larger the ball
diameter, the greater the EWL (see figure below).
A Overall working length
B EWL
C Ball / stem clearance
EWL can also be affected by assembly tolerances. For this reason, Renishaw styli are assembled to exacting standards in controlled
conditions.
Trigger force
Trigger force is the amount of pressure applied by the helical compression spring onto the pivotal plate and bearing points to hold the stylus
mount in place.
The trigger force is preset by Renishaw but can be altered for any of the following reasons:
to permit the use of longer styli on the probe
to permit the use of heavier styli on the probe
if the preset trigger force has decreased due to probe use
if the acceleration of the CMM is causing illegal triggers
NOTE: Changing the probe trigger force will affect the probe's measurement performance. It is important to requalify the probe
configuration and check the measurement performance of the probe system after any adjustment has been made to the trigger force.

All Renishaw's touch-trigger probes have an optimum trigger force setting for general purpose applications as detailed in the table below.
Trigger force:
CMM probes Stylus length (typical) Optimum trigger force (preset by Renishaw) Trigger force range
TP1(S) 31 mm (PS1-1R) 0.15 N 0.1 N - 0.5 N
TP2-5 way 10 mm (PS12R) 0.07 N - 0.08 N 0.07 N - 0.15 N
TP6 / TP6A 21 mm (PS1-12R) 0.11 N - 0.13 N 0.11 N - 0.3 N
Checking trigger force with the Renishaw gram gauge
1. Ensure that the probe is held firmly in position (preferably on a CMM) and connected to an interface to detect a probe trigger.
2. Establish the direction of trigger which gives the minimum resistance. The most practical way of doing this is to gently deflect the stylus
with a finger, trying different directions. There are three lobes which produce three maximum and three minimum force directions. These can
easily be found with a minimum of practice.
3. Set the gram gauge maximum force indicator to the zero point and place the gram gauge flat on the CMM table. Move the stylus tip to the
same height above the surface as the gram gauge lever.
4. Slide the gram gauge slowly sideways so that the flat point on the end of the lever touches the probe stylus ball (ensuring that the probe is
deflected in the low force direction). Very slowly continue to move the gram gauge until the probe triggers, at which point stop immediately,
back off the gauge and read the maximum force indicator.
5. Repeat this procedure three or four times to ensure consistent results.

waymicro‘D'connector,thuspermittingtheuseoftheRenishawTP7highaccuracytouchtriggerprobeandOPT6Mopticaltouchtrigger
probe.
The PH6M incorporates the following primary components and is supplied with the following tools:
PH6M probe head [1]
2.5 mm AF Allen key [2] (for tightening shank socket screws)
Shank [3]
Probe status LED [5]
Autojoint adaptor [6]

The probe head can be used with all Renishaw standard CMM touch-trigger probes and accessories. It can also be used with the PAA
adaptor and M8 extension bars.
Locking and unlocking the autojoint is performed either manually using the S10 joint key [7] supplied, or automatically using the Renishaw
autochange system. This allows probes to be changed without the need to requalify.
The status of the probe is indicated by the probe status LED [5]. This is normally lit when the probe is ready for use and extinguishes as the
probe triggers.

Installing a manual probe head
Fitting an M8-threaded CMM touch-trigger probe to a manual probe head
Fit an M8-threaded non-autojointed CMM touch-trigger probe to a manual probe head as described below:
NOTE: The PH5 and PH5/1 probe heads contain five M8 probe sockets. Each socket that does not contain a probe must be fitted
with a socket cover and insulating washer.
1. By hand, screw the threaded end of the touch-trigger probe into the M8 bush of the manual probe head and hand-tighten to secure.
2. FittheS1‘C'spanner(supplied)tothetouchtriggerprobeasshownbelow.
3. Use the spanner to tighten the touch-trigger probe into the M8 bush.
The S1 C' spanner is designed to break before any damage can occur to either the probe or the probe head due to over-tightening
the probe.
Do not use any other tool to tighten the probe in the probe head as this could result in damage to both the probe and the probe head.
Fitting an autojointed CMM touch-trigger probe to a manual probe head
The repeatability of the Renishaw autojoint ensures that a probe need only be qualified once. The qualification data can then be recalled
whenever the probe is re-attached.
Fit an autojointed CMM touch-trigger probe or PAA series adaptor to a manual probe head as described below:
1. Check that the locking cam on the autojointed probe is in the unlocked position (the slot is horizontal).
2. Offer up the autojointed probe to the PH6M, ensuring that the alignment marks on both the probe and the probe head are correctly
aligned.
NOTE: If the TP6A touch-trigger probe is to be used in conjunction with the Renishaw autochange system, the TP6A should be
lockedtotheprobeheadbyrotatingthecamfullyclockwiseandthenreversingitby5°.
3.InserttheS10jointkeyintothecamoftheautojointedprobeandrotateclockwise(120°)tolocktheprobetotheprobehead.

Attaching a shank to a manual probe head (except PH6)
Renishaw products may incorporate either three or four tapped holes to facilitate fitting a shank. Renishaw shanks are supplied with five
holes to allow either three-hole or four-hole products to be fitted to them.
Attach a Renishaw shank to a Renishaw manual probe head as described below:
1. Locate the shank on to the top of the probe head.
2. Align the holes within the shank with those within the probe head.
3. InsertanM3×6mmAllencapscrewintoeachofthethreeorfourtappedholesandhandtightenusingthe2.5mmAllenkeysupplied.

Troubleshooting
If you experience problems which you are unable to identify or solve satisfactorily, please contact your Renishaw representative for further
advice or contact the Technical Support Department at any Renishaw office for free assistance by telephone (see address list on rear
cover).
Poor measurement performance:
Possible cause Solution
Probe or probe extension bar not installed correctly. Remove probe and / or probe extension bar and re-fit using the S1 spanner.
Stylus configuration too long or not rigid. Use shorter / stiffer stylus configuration.
Poor stylus assembly. Ensure that the number of stylus joints is kept to a minimum and all joints are clean
and secure.
Contaminated / damaged stylus ball. Inspect for damage, clean thoroughly with solvent.
Trigger force too high. Decrease trigger force to the minimum necessary to ensure reliable triggering.
Too few points taken for probe qualification /
measurement.
Take a larger number of points on the qualification / feature measurement.
Unwanted triggers during CMM movement:
Possible cause Solution
Trigger force set too low. Increase trigger force to the minimum necessary to ensure reliable triggering.
Stylus configuration too heavy. Reduce mass of stylus configuration.
Reduce stylus length to minimum possible.
Use a lightweight material for stylus configuration (GF or ceramic).
No probe signal:
Possible cause Solution
Probe not installed correctly. Remove probe and re-fit using the S1 spanner.
Probe extension bar failure. Check connections and integrity of probe extension bar.
Contact your CMM supplier or Renishaw representative for further assistance.
